There's a really cool book out called "It's Easy Being Green" written by Crissy Trask. The book gives tons of great ideas about how you can 'be green' in everyday life without having to give up basic comforts or turn your life upside down. It's full of smart ideas.

And her website is here:

I haven't explored the website much, but if its anything like the book - it's probably practical and useful.
